Meet 17 year old Rebecca with whom everything just seems to be going wrong. Her family appears to have a deep rooted hatred for her, her 'boyfriend' constantly pressures her into having sex and for some reason she can't seem to stop daydreaming about Jack Reys. "On days like this, I wish God would have mercy on me by ending my meaningless existence" Can you imagine what happens when a horde of otherworldly 'men' shadowed by masks attack the UK? All those 21 and under have been deemed worthy of being saved so are taken to a safe house, but not Rebecca - she's been forgotten; left behind. The only thing she can do is to get away from the impending danger and with another woman's 6 year old child, a 9 year old girl, a 'man' shadowed by a mask and a bloody, sulking, temperamental 18 year old, how on Earth is she going to find her way out of the end of the tunnel? Looks like she's on the run.
